Homing in on sources of electromagnetic transmissions has been a thing since at least the BV246 in 1943.
The first phased array systems date back to 1905.
We have had some time to productionize this.
Hell, the "PA" in "PATRIOT missile" stands for "Phased Array".
- IshKebab 3mo agoI'm not saying it's new technology. The patriot missile costs $4m each. None of the drones Ukraine is using have this tech. The new thing is that it's available for purchase for a reasonable price.
- shakow 3mo agoWhy would they put phased arrays on UAVs? They are typically using beam-forming antennas + cheap gimbals for the same purpose. Phased arrays are nice when you want to scan a large angular surface very fast; when it comes down to optimizing RF radiation toward your ground station, a gimbal is cheaper, simpler, and works fine.
